ABSTRACT:
In the new plant for finger-jointing wood-boards described herein, dielectric heating is applied to the crude ends of the boards before the fingers are cut in them. The ends of the boards only are fed in and out of the dielectric heating means and conveyed to finger cutting means where fingers are cut in the heated ends. Glue is applied to the hot cut fingers and assembling and pressing together of the hot glue-coated fingers is performed rapidly. The curing of the glue is provided by the heat accumulated in the ends of the boards.
